30-Day Free Evaluation

Product Selection

I am interested in evaluating:

ClearOS Professional Lite
ClearOS Professional Basic
ClearOS Professional Standard [most popular]
ClearOS Professional Premium

Before you get started...

  1. ClearOS requires dedicated hardware to run on (unless you are installing on a hypervisor). ClearOS is an Operating System (OS). It is not an application that runs on an OS like Windows.
  2. We recommend an x86 processor, 1GB RAM and 5GB hard drive space as a minimum for running ClearOS. For more information, click here.
  3. ClearOS will install over and erase your server/PC's hard disk. Any data on this hardware will be irrecoverably lost.
  4. Technical support is available during your trial, albeit, on a limited basis. We will make best efforts to respond to your inquiry in 2 business days and assist you so that you can properly evaluate ClearOS. Please use the ClearCARE support ticket tool available here.
